Dyslipidemia, insulin resistance and diabetes are frequent in patients on highly active anti-retroviral
therapy (HAART) and especially in patients with lipodystrophy, and may lead to atherosclerosis. This
study described the metabolic alterations associated with lipodystrophy in adults on chronic HAART in
Kenya. The prevalence of dyslipidaemia amongst the study participants was (211) 79.6%. Elevated total
cholesterol was found in 129, high low-density-lipoprotein cholesterol (LDL-C) in 107, low High-density
lipoprotein cholesterol (HDL-C) in 110 and high triglycerides in 131 participants. Lipodystrophic
patients were more likely to have dyslipidemia than normal lipids (55.4 versus 35.1%, p = 0.007 OR 2.2
CI 1.3 to 4.6) with 57, 45.9, 65.9 and 45.2% having elevated total cholesterol, elevated LDL-C, elevated
triglycerides and low HDL-C, respectively. Hypertriglyceridemia and hypercholesterolemia were
significantly associated with lipodystrophy (OR 3.8 CI 2.3 to 6.4; p = 0.000) and (OR 1.94 CI 1.2 to 3.2; p
= 0.008), respectively. The odds of lipodystrophy was 2.913 times higher for patients with elevated
triglycerides than for those with normal triglycerides (p < 0.001). Sixty-four (24.3%) participants had
dysglycemia, with 3.5% having diabetes and 20.8% having impaired fasting glucose (IFG). Among
patient with lipodystrophy, 69.8% had normal fasting glucose, 25.1% had IFG and 5.1% were diabetic.
Lipodystrophic patients were not more likely to have abnormal blood sugars than normal blood sugars
(p value 0.125).

Otieno CF, Huho AN, OEOAAANE.  2008.  .Type 2 diabetes mellitus: clinical and aetiologic types, therapy and quality of glycaemic control of ambulatory patients.East Afr Med J. 2008 Jan;85(1):24-9.. East Afr Med J. 2008 Jan;85(1):24-9. : African Wildlife Foundation. Nairobi Abstract

BACKGROUND: Type 2 diabetes is a heterogeneous disease with multiple causes revolving around beta cell dysfunction, insulin resistance and enhanced hepatic glucose output. Clinical judgement based on obesity status, age of onset and the clinical perception of residual beta cell insulin secretory function (hence insulin-requiring or not), has been used to determine therapeutic choices for each patient. Further laboratory testing of the clinically defined type 2 diabetes unmasks the various aetiologic types within the single clinical group. OBJECTIVE: To determine the aetiological types of the clinically defined type 2 diabetic patients, their chosen therapies at recruitment and the quality of glycaemic control achieved. DESIGN: Descriptive cross-sectional study. SETTING: Diabetes out-patient clinic of Kenyatta National Hospital, Nairobi, Kenya. RESULTS: A total of 124 patients with clinical type 2 diabetes were included, 49.2% were males. The mean duration of diabetes in males was 26.09 (20.95) months and that of females was 28.68 (20.54) months. The aetiological grouping revealed the following proportions: Type 1A-3.2%, Type 1B-12.1%, LADA-5.7%, and "true" type 2 diabetes 79.0%. All the patients with Type 1A were apparently, and rightly so, on "insulin-only" treatment even though they did not achieve optimal glycaemic control with HbA1c % = 9.06. However the study patients who were type 1B and LADA were distributed all over the treatment groups where most of them did not achieve optimal glycaemic control, range of HbA1c of 8.46 -10.6%. The patients with "true" type 2 were also distributed all over the treatment groups where only subjects on 'diet only' treatment had good HbA1c of 6.72% but those in other treatment groups did not achieve optimal glycaemic control of HbA1c, 8.07 - 9.32%. CONCLUSION: Type 2 diabetes is a heterogeneous disease where clinical judgement alone does not adequately tell the various aetiological types apart without additional laboratory testing of C-peptide levels and GAD antibody status. This may partly explain the inappropriate treatment choices for the various aetiological types with consequent sub-optimal glycaemic control of those patients.

BACKGROUND: Diabetic ketoacidosis is the most common hyperglycaemic emergency in patients with diabetes mellitus, especially type 1 diabetes. It carries very high mortality in sub-Saharan Africa, both in the treated patients and those who are presenting to hospital with diabetes for the first time. OBJECTIVE: To review the risk factors, mechanisms and management approaches in diabetes ketoacidosis in published literature and to discuss them in the context of why a significant proportion of patients who develop diabetic ketoacidosis in sub-Saharan Africa still have high mortality. DATA SOURCE: Literature review of relevant published literature from both Africa and the rest of the world. DATA SYNTHESIS: The main causes or precipitants of DKA in patients in SSA are newly diagnosed diabetes, missed insulin doses and infections. The major underlying mechanism is insulin deficiency. Treated patients miss insulin doses for various reasons, for example, inaccessibility occasioned by; unavailability and unaffordability of insulin, missed clinics, perceived ill-health and alternative therapies like herbs, prayers and rituals. Infections also occur quite often, but are not overt, like urinary tract, tuberculosis and pneumonia. Due to widespread poverty of individuals and nations alike, the healthcare systems are scarce and the few available centres are unable to adequately maintain a reliable system of insulin supply and exhaustively investigate their hospitalised patients. Consequently, there is little guarantee of successful outcomes. Poor people may also have sub-optimal nutrition, caused or worsened by diabetes, more so, at first presentation to hospital. Intensive insulin therapy in such individuals mimics 're-feeding syndrome', an acute anabolic state whose outcome may be unfavourable during the period of treatment of diabetic ketoacidosis. CONCLUSIONS: Although mortality and morbidity from diabetic ketoacidosis remains high in sub-Saharan Africa, improved healthcare systems and reliable insulin supply can reverse the trend, at least, to a large extent. Individuals and populations need empowerment through education, nutrition and poverty eradication to improve self-care in health and living with diabetes

ENOCH, DROMONGE.  2005.  Acute aflatoxicosis: case report. East Afr Med J. 2005 Jun;82(6):320-4.. East Afr Med J. 2005 Jun;82(6):320-4.. : African Wildlife Foundation. Nairobi Abstract
The objective of this presentation is to document the salient clinical findings in a case of aflatoxicosis and to review the literature on the same so as to increase the index of suspicion, enhance early diagnosis and improve management. The case was a 17-year-old schoolboy presenting with vomiting, features of infection and gastrointestinal tract symptoms. Examination revealed a very ill looking pale patient with abdominal distension, tenderness and rectal bleeding and easy bruisability. Investigations showed abnormal liver function tests, pancytopenia and elevated serum levels of aflatoxins. Management consisted of supportive care including antibiotics and antifungal therapy, transfusion of red blood cells and fresh frozen plasma. His recovery was uneventful. The literature on human aflatoxicosis shows that the presentation may be acute, subacute and chronic. The degree of emanating clinical events also conforms to status of the aflatoxicosis. Overall, the features are protean and may masquerade many other forms of toxaemias. In conclusion, the diagnosis of aflatoxicosis takes cognisance of geographical location, past events, staple diet and clinical features to exclude other infections. Also required are high index of suspicion and importantly serum levels of aflatoxin. Treatment strategies involved use of antimicrobials and supporting the damaged multi-organs.


ENOCH, DROMONGE.  1998.  Clinical and laboratory predictors of cholelithiasis in patients with sickle cell anaemia .East Afr Med J. 1998 Jun;75(6):347-50. East Afr Med J. 1998 Jun;75(6):347-50. : African Wildlife Foundation. Nairobi Abstract
Cholelithiasis is a common clinical condition in patients with sickle cell disease and there are conflicting reports on laboratory indices useful in predicting those patients who are likely to have gallstones. There is however lack of similar studies from Kenya. We therefore studied the role of clinical (Body Mass Index), haematological (reticulocyte count, haemoglobin level), and biochemical (serum bilirubin: direct and indirect, serum alkaline phosphatase, serum transaminase) indices in predicting sickle cell anaemia patients likely to develop gallstones. A cross sectional descriptive study was conducted from October 1993 to December 1994 on consecutive male and female patients of all ages with homozygous sickle cell disease (HbSS) confirmed by cellulose acetate paper electrophoresis. A total of 64 patients aged between three and 37 years were recruited into the study. They were classified into two groups: stone formers and non-formers. The difference in the two groups with respect to clinical, haematological and biochemical indices were determined by Chi-square contingency test. Body mass index (BMI), reticulocyte count and alkaline phosphatase were found to have a significant positive association with increased likelihood of gallstone formation at p values of 0.004, 0.007 and 0.007, respectively. The rest of the study indices had no association. The cut-off points were reticulocyte counts above ten per cent and alkaline phosphatase levels above 13 K.A. units. Though sickle cell anaemia patients with BMI > 20 had significant increased likelihood of cholelithiasis, we could not determine its cut-off value.
